ton 15A and1 16, respectively, by which said shafts may be -moved'endwise manually.

.Disposed vthrough each of the shafts 9 and 10 are pins 17. and 18respectively, same'being located to therigh't of brackets 7 and 8."

respectively, and they form stops, preventing shafts 9l and 10 frombeing inserted too far into the ,rol-1ers. Encircling shaft 9" andpressing against pin 17 and bracket 7 is the helical spring 19; andencircling shaft 10 and pressin against pin 18 and bracket 8 Ais thehelica spring 20, said springstendin to normally retain. the inner endsof sai shafts inserted in the ends of the rollers and therefore.retaining the rollers resilient-ly in operative position, but adaptedto be removed lat any timeby ,moving said butto-ns and 16 to the right.Mounted below and a little forward-of roller-5 is Ythe upper smallroller21 which is slightly longer than roller "5, and it is carried bysuitable hangers 22 cured on the fouter end of 4shaft ,10, is the bevelgear wheel 28.

Numeral 29 denotes a vertical shaft located at right-angles to saidshafts 9 and 10 and at the left thereof, same being mountedin suitablehangers 30 and 30 which are secured to the base 1, and said shaftextends down ,below the lower edge of the base 1, with a hand-wheel 31secured on its lower end whereby said shaft may Abe operated manually.Secured on the upper end of shaft 29 is the bevel gear wheel 32 which isadapted to mesh with the bevel gear wheel 27. Also secured on shaft 29`isthe bevelgear wheel 33 which is adapted to mesh with the bevel gearrwheel 28. The wheels 32 and 33 are so located that only one of them may'be in mesh at lone time, depending onl whether shaft 29 be 'moved up ordown to its limit of endwise movements.

Loosely mounted around .shaft 29, a short distance above hand-wheel 31,is the thimble 3,4,which has a cam-like projection 35` extending upwardand engaged by spring 36 v A which retains the thimble ,up to its limit.

.Thimble 34 has a fiange on its lower end whereby it may be moved withones fingers in order to throw the latch37 out of engage- Imentwith oneof the two grooves formed `around in shaft'f29, this being caused by the.rear -part of thev central portion of the hollow stern of the thimble`34 engaging as a .,T. l'cam therighthand portion of latch 37 andforcing it forward away from shaft 29 andy retaining it away from shaft29 until the thimble 34 is released after which spring-36 will raisevthe thimble 34 andvallow the latch 37 tobe forced against shaft 29 byspring 38 and consequently causing the right-hand end of the latch 37 toenter one of the grooves in shaft 29 when one of said grooves is broughtopposite thereto by the movement up or down of. shaft 29, by which theshaft 29 is retained in one or the other of the two positions required(up Vor down) to cause the bevel: gear wheels 32 and 33. to be engaged-with their respective gear wheels 27 and 28. Said latchv 37 yisretained in re` silient contact With sha`ft 29 or in one of said groovesin shaft 29 by means of the spring 38, substantially as indicated.

Numeral 39 denotes a spool whichis revolubly mounted on shaft 29, samebeing-l prevented from sliding downward by means of the collar e whichis secured to the shaft 29, there being a stem 39 formed integral withsaid spool 39 which extends down around shaft 29 tosaid collar e. Ahelical Spring 40 is 'coiled around 'the stem 39', one end of saidspring being secured to spool 39 and the other. end of said spring issecured by the screw 41 to the base or back 1. Coiled around'on thespool 39 is the cord 4 above referred to, the inner end of saidy cordbeing, secured to the spool and the outer end there-l Aof hanging freeoutside of the face of the cap where it may be grasped by the operator.The lower flange of spool 39 has about one-fourth of itsperipherycut-away or indented, as shown in Fig. 5, also there being a lug gformed to extend out farther than ie periphery as shown which lug'isadapted to be engaged by the upper end of the post 42, the latter beingsecured tothe basel. A brush 43 is secured tothe base 1 with a iexibleportion extending upward and adapted to travel on the normal peripheryof the lower flange of spool 39, but it does not engage with .theperiphery of the lower or cutaway portion 'of said flange.

Numeral 44 denotes a small ratchet wheel mounted on shaft 29 adjoiningthe upper flange of spool 39, and formed integral with ratchet-Wheel 44is the larger ratchet-wheel 45 located thereabove. A pawl 46 is pivotedon the upper end of spool 39 and is adapted to engage' the teeth ofratchetwheel 44.

. Carried by post 47 is the magnet 48 having the armature 49, thelatterbeing carried by the arm 50. Arm 50 is pivoted in hanger 51 whichis attached to base 1. The lefthand end of arm 50 forms a pawl which isadapted 'to engage the notches in the ratchetwheel 45. The arm 50 isnormally retained out of -engagement with ratchet-wheel 45 b v means ofthe spring 52 which is secured thereto and to the-base 1, italsonormally retains the armature Y4 9 from Contact wit y:and I the roller24, nearthe right-hand end .there-' f CQIIta-'Ctwband n:

As the operator now .releases cord-libe spring 40 will lrevolve thespool-' .-3%3 i$ck aPPe-aring' -ss 5 t-hereby drawing. thefrib-. I l'bon' upward, and from' olf lroller .6( N ow as the ribbon 63v movesupward. the word.' 105 this time t-he brush 43 will, manifestly, be

This last movement will ofcourse break the elec-y the magnet' by the'spring 52, and yalsoreleasing the point. of arm 50 from engagement with ratchet-wheel 45. Asstation Hillyard. islpassed-mthe operator will again pull cprd i causingthe ribbon to again. move upward until the word f Colbert lis infullview, when the .electric circuit will again 4 be established forminga complete circuit l5` thereby stoppingy further movement as before.When all of the stations `have been passed -in one. direction, or `forany `other reason one desires to reverse the movementof the r1bbon,.then.all that is necessary 1s furthe operator to grasp the hand-wheel 31,with his fingers' pull down on the thimble 34 which releases the latch37, and then pull n downward until the latch 37engages in the uppergroove yof the two formed in shaft 29,- whichq will move the gear Wheel32 out of engagement with gear wheel 27, and at,j

same time moving gear wheel 3,3 into engagelnent with gear wheel28.After the last named movements it is Fapparent that bypulling the cord 4the ribbon will operate downward, as it ,will be wound upon roller6.therebycausing the names of the stations fto appear inv reverse order.l

By reason of the above described construction, lwhereby themovementsofthe ribbon `is stopped electrically at the proper point,it is apparentthat we overcome previous diiiiculti'es, as in this' instance theconstantly lincreasing volume of ribbon accujmulating on one or theother of rollers 5 and 6 Willmake no difference in the operation of thedevice. When it is desired-to change they ribbon for one -with differentstation names, then the front of the case may be opened, the old ribbonis all wound on one roller, roller 5for instance, byY turning hand-wheel31,

then by pulling to the right on button 15, against the resiliency ofspring 1 9, the shaft 9will` be pulled out of the end of the roller 5vfar enough so that the roller maybe lifted out. The roller carrying thenew ribbon is next placed .with vslotted end on the en'd of shaft 9,then swung into line'and shaft 9 allowed to spring/back into place. Theend of the ribbon is next carried over rollers 21,; 23 and 24,and thenconnected to'roller 6, and the device l,will'then be ready foroperation.

essais We desire that it be understood that while .Having now fullyshown andl described :our invention and its operation, what we :claimand desire tosecure by Letters Patent fof the United States, is-' Astation indicator comprisinga base llaving a casing provided with asight o ening,

l a ribbon with the names of stations t ereon, a pair of revolublerollers mounted in the g casing and having said' ribbon wound thereon, ashaft adapteldto be operatively enfgaged with either of said rollersinde .endently for rotating the latter in reverse irections, mean forrotating the shaft to present one of the names at the opening andcomprising in' part a rotatable spool having ia partially recessedperiphery andmeans g for automatically stopping the ribbonsimultaneously with the appearance of a nameat the opening, said meanscomprising an elecl -trical circuit having a suitable source of power, apair of guide rollers adjacent Aone of said ribbon carrying rollers forreceiving the ribbon, a Contact band carried by one of said guiderollers, another roller mounted adjacent said bandcarrying guide roller,a
